Performance characteristics
Improve the dispersion of silica and inorganic fillers in matrix rubber, promote the interface bonding between silica and rubber, improve the dispersion of various powders in the rubber, and bond with the silanol groups on the surface of silica , significantly improve the tire's wet skid resistance, low rolling resistance, high elasticity and other properties, the wear amount is more than 15% lower than similar domestic products, and is superior to foreign silica dispersants.
Product appearance
light to light yellow granular solid
Composition and category
Organoboron fatty acid amide, a chelating coordination coupling dispersant
Usage and dosage
Suitable for synthetic rubber and natural rubber, mainly used for tires and rubber products. RF-2 can be added directly during the rubber mixing process. The adding ratio is RF-2/silica =1/(20-25) .
Packaging and storage
Three-in-one paper-plastic composite kraft paper bag, stored in a cool and dry place, with a shelf life of two years.
